Recently I got the 4G sim for my phone but when I searched the network of 4g there was no network but there was 3g network I live on 2nd floor but till no 4g in my room I have to go out from the room to terrace to use 4g the speed is very slow its like 3g 2mbps which is not good speed in terms of lte connection and when I visit open network there it says there is tower near to me, airtel is one of the loser doing fake promises to its users and the customer care is worst you have to wait so much you will get frustated guys if you want to use 4g lte get jio sim its cheap and fast
